Tefal X-ploter Serie 60 Replacement Battery 14.4V 6700mAh

Tefal X-plorer Serie 60 — 14.4V Li-ion Replacement Battery

This is a 14.4V, 6700mAh Li-ion replacement battery for the Tefal X-plorer Serie 60 cordless stick vacuum. It replaces the original pack when the vacuum no longer holds a charge or suction drops off within minutes of starting. Capacity comes in at 96.48Wh — matching the original power draw requirements of the Serie 60 motor.

• Serie 60 motor compatibility: The X-plorer Serie 60 runs a brushless motor that draws current in bursts — especially when switching between floor and carpet modes. This 14.4V pack matches the voltage rail the BMS expects, so the motor controller does not flag a low-voltage trip on startup or during high-draw transitions.
• Bench tested on actual hardware: We cycled this pack through multiple discharge runs on a Serie 60 unit, monitoring BMS cutoff behaviour under a blocked filter condition. The cell group held voltage above the 12V cutoff threshold consistently and recovered cleanly after each thermal reset.
• Dock charging discipline for the Serie 60: The Serie 60 charging dock does not cut power once the pack reaches full — it trickle charges continuously. Remove the vacuum from the dock once charging is complete. Leaving it docked permanently degrades cell capacity faster than normal cycling does.

Suction dropping before the battery indicator shows low

This is not always a battery failure. When the filter is partially blocked, the motor works harder to maintain airflow and pulls more current than the BMS allows under sustained load. The BMS reads that overcurrent spike as a low-cell condition and reduces power output to protect the cells — even if the indicator still shows two or three bars. Clean the filter first. If suction restores and the indicator stays stable, the battery is not the cause. If the vacuum still sags with a clean filter, the cell voltage under load is likely dropping below 12.6V, which points to a degraded pack.

Battery not charging after fitting the replacement pack

Some Serie 60 chargers perform a handshake with the BMS before delivering current — if the BMS does not respond within the expected window, the charger stays in standby and no charge light appears. Seat the battery firmly and leave it on the dock for at least 10 minutes without moving the unit. If the charge indicator still does not activate, check the dock contacts for oxidation and clean them with a dry cloth. A confirmed 0V reading at the dock contacts means the charger itself needs replacing, not the battery.
